What do you mean bitstreaming?
I do not use amplifier
Right now i opened the Audio Settings in the Reclock Configuration and i see that i have put ( Bitstream at Direct Sound ) , and down in the other oprion (Accept bitstreams formats) , is unchecked

Please note that in all the Chroma upscalings , i have put super-xbr 100
In 1080p and 720p everything is perfect and only in SD creates problems

You think that i have to create something different at the display modes?

EDIT
I forgot to report that it happens in all videos with resolution below 720x576 i.e SD480
I have to add something in the display mode?
Thanks
